Antique Georg Kreuzberg Mineral Water Stoneware Bottle German Glazed 1800s No.65

Description

Here is a  1800's Antique Georg Kreuzberg Mineral Water Stoneware Bottle.. This 12.25" bottle looks to be glazed. I filled it with water and got 40oz in it, this filled it to right below the neck of bottle. Bottle is in nice shape, the number on it is either 65, or 6. i am not sure, it has a script marker on the other side, so i dnt know if the script is repeated or that is a 5.. The  vessel seem to have a crack in the glaze.. I don't tjhink it is in the bottle itself, because once filled with water it did not leak, I left water in it for a bit.. I know nothing about pottery, this actually came to me in a box of towels, I got at an estate auction, i thought it was neat and maybe somebody would like to add it to their collection. Guessing by the letters, I think this is a German bottle..
